Proteins

Not quite remember

I easily remember

Elements of proteins

Carbon, hydrogen, oxygen, nitrogen, sulphur and phosphorus

Monomer of proteins

Amino acids

Polymer of proteins

Polypeptides

Dipeptides

1) Consists of two amino acids linked by a peptide bond through a condensation process 2) Dipeptide molecules can be broken down into two amino acids through the process of hydrolysis

The number of naturally occurring types of amino acids

20 types of amino acids

Condensation of amino acids

Remove one molecule of water to link two amino acids to form a dipeptide

Hydrolysis of dipeptides

One molecule of water is used to break down dipeptide into two amino acids

Importance of proteins (1)

Build new cells, repair damaged tissues, synthesizes enzymes, hormones, antibodies and hemoglobin

Importance of proteins (2)

Proteins also form building blocks such as keratin in the skin, collagen in bones and myosin in muscle tissues

Importance of proteins (3)

The breakdown of proteins or polypeptides by digestive enzymes gives us the energy to carry out our daily activities
